IMPROVEMENT IN MACHINES FOR GALVANIZING'TE'RNE PLATES- Specificationforming part of Letters Patent N 0. 185,034, dated December 5, 1876;application filed September 9, 1876.

To all whom it may concern:

Be it known that we, JOHN D. JoNEs and JOHN GAPE, of Audenried, in thecounty of Carbon and State of Pennsylvania, have invented a new andImproved Machine for Galvanizing Iron Plates and Hoops, of which thefollowing is a specification:

Figurel is a side elevation in section, taken on linea' min Fig. 2. Fig.2 is a top view.

Similar letters of reference indicate corresponding parts.

Our invention relates to that class of machines which are used incoating or galvanizing sheet-iron and it consists of an iron receptaclefor the melted metal, in which two sets of rollers are placed, which areactuated by a spur-wheel, which meshes into pinions on theroller-shafts. Au inclined guide-plate extends down to the rollers;this, together with a table between the sets of rollers, and an inclinedguide-plate beyond, forms a way on which the plates or hoops move intoand out of the melted metal. Another pair of rollers is placed at theend of the last-mentioned plate, to remove the superfluous metal.

A is a receptacle for the melted metal, in which a frame, B, is hingedon swinging bars a a, so that it may be raised up out of the receptacleby swinging it on the bars. 0 O are rollers, having fixed journal-boxesin the frame A, and provided with spur-pinions b b. D D are rollers,which are placed above the rollers O U, and rest upon them, and areprovided with adjustable journal-boxes m, that slide in ways in theframe B, and are regulated by 1 the screws d. E is a spur-wheel, that isattached to the shaft 0, having the journal-box F on the side of thereceptacle A. The wheel E meshes into the pinions b b. G is an inclinedguide-plate, which extends from the upper part of the frame B nearly tothe point of contact between the rollers O and D. This plate is providedwith ears f, which drop into notches in the frame 13. The upper end ofthe plate rests against the rear end of the frame B. H is a table, whichis coved at each edge to conform to the rollers O O, and rests on aprojection on the frame B. Iis a guideplate supported by the ears g,which rest in notches in the frame B. It also rests on the partition J,which runs across the end of the receptacle A. K L are rollers, whichare supported on the receptacle A in such a position that their point ofcontact will be nearly in line with the upper surface of the guideplateI.

A pulley, h, is placed on the shaft which supports the roller K, and isdriven by a belt that passes around a wheel, M, which is attached to theshaft e. The roller L is provided with adjustable journal-boxes '5,similar to those on the journals of the rollers D .D. A cover, N, isplaced over the rollers K and L, to prevent the escape of heat. Theframe B is retained in place by the cross-bar O, which is let into thesides of the receptacle A, and notched to embrace the frame.

The operation of our invention may be described as follows: Thereceptacle is placed overa suitable fire, and a temperature maintainedwhich is sufficient to keep the metal placed therein in a melted state.A quantity of metal is placed .in the receptacle which will partly orwholly cover the rollers D D. Chloride of zinc is placed on the surfaceof the metal, so that as the sheet is immersed in the metal it receivesa coating of flux. As therollers C- O and D D are revolved the sheet iscarried through the metal by them and delivered to the rollers K L,which, being hot, remove the superfluous metal and deliver the sheets ina finished condition. The shaft 6 is capable of sliding, so as todisengage the wheel E from the pinions b b, when the frame B can beraised out of the receptacle A, and the various parts can be removed forcleaning or other purposes.

The advantages claimed for our invention are that it effects a greatsaving in time and material, and consequently reduces the expense ofmanufacture.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. The combination of two sets of rollerspartly or wholly immersed in melted metal, with guide-plates leading toand from the said rollers, the whole supported on a removable frameplaced in a receptacle for the melted metal, as shown and described.

5. The combination of the adjustable journal-boxes m and i, rollers D,D, and L, and

frame B, substantially as specified.

6. The combination of the receptacle A, frame B, bars a, and cross-barO, substantially as specified.
